| Weld Neck Flange | Designed for high-pressure applications, this flange is welded directly to the pipe. | Oil & gas pipelines |
| Slip-On Flange | Fits over the pipe and is welded in place, ideal for low-pressure systems. | Water and wastewater treatment |
| Blind Flange | Used to seal the end of a piping system, not designed for pressure application. | Pipe repairs and maintenance |
Influencers such as James J. Sullivan, a renowned piping systems engineer, emphasize the relevance of selecting the correct flange type for enhanced system integrity.
2. Fitting Types
| Type of Fitting | Description | Common Use |
|---|---|---|
| Elbow Fitting | Allows for a change of direction in the piping system, commonly at 90 or 45 degrees. | Piping around corners |
| Tee Fitting | Creates a branch line from the main pipeline, either in a straight or angled direction. | Connecting multiple pipelines |
| Reducer Fitting | Used to connect pipes of different diameters, allowing for smooth transitions. | Step-down in process applications |
Experts like Linda K. Chen, a notable mechanical engineer, recommend understanding the function of each type of fitting to prevent flow issues and leaks.
